Claims (6)

1. The bioactive mixture preparation process that regulates drug release, which consists of an integral part. Is to emulsify / diffuse pesky remover Which may choose to keep the clay on the inert volumetric compound In the polyhydroxybenzoate polymer acquias system Where the polymers Is the flour that has not been processed Adding water-soluble alkali metals or magnesium, and an inert volumetric additive may be added while mixing together to yield flocculation, to dry the sedimentation yield. And grind the product to the desired particle size 2. The bioactive mixture preparation process that regulates drug release, which consists of an integral part. Is to emulsify / diffuse pesky remover On or in combination with soluble alkali metals or magnesium sulphate with inert volumetric additives that may be chosen in polyhydroxybenzoate acidification systems. Where the polymer is Unprocessed flour Dry the produce after settling from emulsion / diffusion. And grind the produce to the desired size 3. The bioactive mixture preparation process that regulates drug release which consists of an integral part. Is to emulsify / diffuse pesky remover On or in combination with soluble alkali metals or magnesium sulphate with inert volumetric additives that may be chosen in polyhydroxybenzoate acidification systems. Where such polymers are unprocessed starch. Another addition of a soluble alkali metal or magnesium sulfate and optional volumetric additives. While stirring the mixture to precipitate, dry the produce and grind the yield to the desired particle size. 4. Preparation process of drug-regulating compound release of pesticides containing soluble alkali metals. Or magnesium sulphate and volumetric additives that may be selected in the medium of a water soluble / puffing polymer system. The process is mainly composed of the precipitation of the mixture from emulsions / dispersants, activates of insoluble pesticides, aqueous polymers, and water-soluble polymers. Where such polymers are unprocessed starch. By adding soluble alkali metal or magnesium sulphate Dry the sediment And grind to desired particle size 5. Mixture in claim 4, where the pesticides are herbicides. 6. Mixture as in claim 5, where the herbicide is Nitro compounds
